Insights
Ulnar longitudinal deficiency (ULD) treatment is challenging. A modified single bone forearm surgery with Ilizarov external fixator distraction achieved stability and improved function in two pediatric patients with ULD Bayne Type II.
Area of Science:
- Orthopedic Surgery
- Congenital Hand Deformities
- Pediatric Orthopedics
Background:
- Ulnar longitudinal deficiency (ULD) is a rare congenital upper limb anomaly.
- Existing treatments lack a gold standard, posing challenges for hand function.
- Bayne Type II ULD involves partial ulna aplasia.
Observation:
- Two pediatric patients (3 and 16 years old) with ULD Bayne Type II were treated.
- A modified single bone forearm surgery was employed.
- An Ilizarov external fixator was used for soft tissue distraction and radius distalization prior to single bone forearm creation.
Findings:
- The modified surgical technique successfully created a single bone forearm.
- The intervention achieved forearm stability and improved hand function.
- Additional limb length gain and improved cosmesis were observed due to the Ilizarov fixator application.
Implications:
- This modified approach offers a potential new treatment strategy for ULD.
- The technique may enhance functional outcomes and aesthetic results in ULD patients.
- Further research is warranted to validate this novel surgical method for ULD treatment.
Abstract:
Ulnar longitudinal deficiency (ULD) is a rare congenital disease of the upper limb. The deformities caused by ULD can be very challenging and may compromise hand function during daily activities. Although the first surgical intervention dates back to the year 1952 there is still no gold standard for treating this uncommon disorder. Two children aged 16 and 3 years with ULD Bayne Type II (partial ulna aplasia) were diagnosed and treated at our department with single bone forearm surgery to achieve stability and improve function using a modified surgical method. For the purpose of an additional gain in limb length and improved cosmesis we used an Ilizarov external fixator for soft tissue distraction including radius distalization prior to the creation of the single bone forearm. This new technique and results are presented and discussed.

Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Bone as Supporting Connective Tissue
Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts—...
